To all whom 2'25 may concern."

' Be it known that I, HARRY Dan MAR, a citizen of the United States, and a resident of the city, county, and'Stat-e of New York, have invented a new and useful Improve ment in Dumb-Waiter Attaclnnents, of which the following is a full, clear, and exact description. I I

My invention relates to improvements in dumb-waiter attachments. Dumb waiters, especiallyin apartment houses, are always badly overcrowded because they are used at only certain hours, and it is very difficult for them to contain and handle the material which. collects on the different floors. The

object of my invention is to provide means for remedying this difficulty, and to produce a simple and inexpensive receptacle which can be conveniently applied to the bottom of the dumb waiter car, and as easily detached, and into which packages, tin cans, bottles, and other materials can be thrown Thus it will be possible for the dumb waiter to be used for handling the commodities, packages, and other things to advantage, while the refuse material can be thrown into the detachable receptacle beneath, and the dumb waiter will not be so badly crowded. Moreover, it will prevent the placing of a lot of this refuse material on the same car with groceries and other things which might be contaminated. Furthermore, it will greatly facilitate the collection of stufi from the several floors, and it can be arranged so that instead of one receptacle, another can be attached below this if necessary.

These receptacles are made light and inexpensive, and are preferably open-on both sides so that material can be thrown in from either side and discharged from either side;

I wish to make it clear that my improvement is used in connection with dumb waiters of the usual or conventional type, and these need not be altered or changed except to provide a clip or attachment on the bottom which will engage a correspondmg or complementary part on the detachable receptacle beneath. This Wlll all be better understood from the description which follows.

Specification of Letters Patent.

Reference is to-be had to the accompanying drawings forming a part of this specification, in which similar reference charac ters indicate corresponding parts mall the views. a

Figure 1 is a broken front view of a dumb water car having a couple of my detachable receptacles'connected therewith.

"Figure 2 is a plan view on the line 2-2 of Figure 1,showing the top of one" of the receptacles. V Figure 3 is a broken view on the line 3-3 of Figure 1', looking up and showing the attachment on the bottom of the dumb waiter n a v Figure 4 is a View looking up on the'line 44 of Figure 1, showing the bottom of one of the receptacles. V

The drawing is by way of example, and illustrates a dumb'waiter car 10 which can be operated by any usual or preferred means, and which will run in a well as usual. To the bottom of the car is attached a, clip 11 having inturned edges 12 on opposite sides, and these are connected preferably at the back by a fiange 12. The inturned flanges 12 thus afford means for engaging the dovetailed tongue 13 on the top 14 of the re-,

ceptacle 15, and the flange 12 prevents the tongue from being pushed too far into the clip 11. Thus it will be seen that the tongue 13 can be readily pushed into engagement with the flanges 12, and thereceptacle 15 will hang from the bottom of the car 10.

I have shown the clip and the engaging tongue as a simple and preferred means of making the connection'between the car and mm omen V ;Patented Jan.10,'1922 Application filed April 19, 192}. Serial No. 462,610. i

the receptacle, but it will be'understood that this idea canbe varied in many ways, and" the important thingis merely to have an engaging means which will be strong enough to support the receptacle and its load, and

which permits the receptacle to be readily attached to or detached from the car. The invention is therefore not limited to the means shown for effecting the above result.

The form of the receptacle is not particularly important, although I prefer a network structure as shown, as this is light and strong, and it is provided with openings 17 on the front and back side, though of course one opening might be used if desired. It-is better to have two, however as the packages or materials'can be thrown in from'either direction and removed in a similar way.

The bottom 16 of the receptacle 15 can be provided with a clip 11 like the clip 11 above referred to, to engage a tongue 13 on the second receptacle 15 and thus two or more receptacles can be suspended from a single car 10, according to the requirements of the house in which the dumb-waiter is used.

In order that the receptacle 15 may not swing, I preferably attach abutments 18 t the under side of the car and on opposite sides of the centre as shown in Figure 1, and additional abutments 18 can be applied to the bottom of the car for the same purpose. V V

In the foregoing description I have .referred to the car 10 as the car or dumbwaiter, and this will be the principal use for the receptacle; but it will of course be understood that if the car 10 were a power driven elevator car, it "could be used in the same way and without any change whatever in construction, andwhen I refer in the claims to the car, it will be understood that it means either the car of a dumb-waiter or elevator.

I claim 1. The combination with an elevator car, of a receptacle having a detachable connection with the aforesaid car.

2. The combination with an elevator car,

receptacle, and means on the top of the receptacle for engaging the aforesaid suspending device.

5. The combination with an elevator car, i

of inturned flanges on the. bottom forming a track, a receptacle, and means on the top of the receptacle for engaging the aforesaid track.
